[SIP Beyond VoIP] A question on presence

I've playing around with the presence while using both the SIP and XMPP domains.
What I do have currently is:
IMS User <-> Open-IMS core <-> SylkServer ( S2S ) <-> ( S2S ) XMPP Server <-> XMPP User
So far Communication on both sides works, SIP <-> XMPP as well as MSRP <-> XMPP
Now the question comes here, how exactly the Presence translation is working with Sylk, if it does of course. E.g. currently My IMS user cannot see the XMPP user online, as same applies for the Opposite as well.
I checked of course the following page:
but to be honest what I see is, that when the Subscribe arrives towards the Sylk from the Open-Ims, Sylk simply answers that it is not acceptable. What might be wrong here ?
>From the other side, when the XMPP user logs into the XMPP server, I cannot see Presenze Stancas being sent towards Sylk ( S2S ) communication, but that's probably due to kind of a configuration.
I do have currently also a SIP presence server which runs on different machine ( e.g. different from Open-Ims Core, XMPP server ). It basically runs on the same machine as the Sylk, but I believe this is not a problem.
I'm using Kamailio as presence server only, which was important to state I guess.
So please, suggestions ?
